Single-output and dual-output power supplies

TOE 8840 – up to 160 WTOE 8850 – up to 320 W

In-phase regulation

A proven concepthas been used for the new, system-compatible single-output and dual-output power supplies of the TOE 8840 and TOE 8850 series. Exceptional specifica-tions are achieved with a total output power of 160 W or 320 W as a result of the classical in-phase control principle. A total of 22 different models deliver voltages up to 130 V and currents up to 20 A. With a resolution of 12 bits in the voltage and current ranges, a simple and convenient user interface, and the excellent specifications, these instruments are suitable for both manual and bus-based modes.

Integrated measurementsA further significant characteristic is the high-resolution measurement of the volt-age and current values; these are output on 4-digit LED displays and can be read at a high rate in bus mode. This means that additional measuring instruments are usually superfluous.

Adjustment using incremental spinwheelsThe output values are adjusted with a selectable sensitivity using wear-free in-cremental spinwheels, thus permitting reliable and precise adjustment of the output voltage and current even after many years of service.

Remote control (option)All instruments can be remote-controlled in analog mode as well as via GPIB and RS 232 interfaces using the SCPI com-mand set (SCPI: Standard Commands for Programmable Instruments). The system interfaces are characterized by a high response and measuring rate. In addi-tion, instrument driver software is avail-able under “LabView“.

Automatic calibrationFast and convenient calibration of all output parameters is possible externally within a few minutes without any adjust-ment of trimmers or interventions in the instrument. This “software calibration“ can be car-ried out simply using the control elements or supported by a computer within a test system. The “software calibration“ pro-vides an advantage which should not be underestimated when considering the regular calibration intervals which are becoming increasingly important in quality assurance systems.

Voltage or current sourceDepending on the values set for the volt-age and current, each power supply can be operated as a voltage source or a current source depending on the load conditions. All outputs can be connected in parallel or series without problem.
